SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 289,973, dated December11, 1883. Application nica May 23,1883. (Model.)

Lhasp being over the staple, the hasp-latchbeing raised, and the sealnot being shown; Fig. 2, a similar view, the hasp-latch being down; Fig.3, a top view ofthe lock; Fig. 4, a front elevation showing, upon anenlarged scale, that portion of the construction with which the seal isimmediately connected; Fig. 5, a horizontal section on the line 5 ofFig. 4; Fig. 6, a vertical section on the line 6 6 of Fig. 5; Fig. 7, a

vertical section on the line 7 7 of Fig. 4; and Fig. 8, a sectional viewof the lock, the front plate being removed.

The saine letters of reference denote the same parts. Consideredgenerally, the principal features of this construction are a hasp, ahasp-latch made to engage in the usual manner with the hasp staple, andalso having a projection adapted to engage with a lockingplate heldWithin a frame upon the hasp, the seal, and a plate for supporting theseal within the haspframe.

A represents the hasp, fastened at one end to the staple B, and at theother end adapted to be passed over the staple C, in the manner in whichhasps are usually operated.

D represents the hasp-latch. It is journaled at d to the hasp, and atthe other end, d', is adapted to engage in the customary manner with thehasp-staple C. It is. also furnished with the projection d, which, inlocking the hasp, is adapted to pass into 'a frame, a, upon the hasp A,as shown in Fig. 2. The projection d2 has one, and preferably a series,of recesses, cl3 d3 d, Fig. 6. l

E represents a plate, held in the frame c so as to be movable toward andfrom the latch projection d2. The most desirable method for this purposeis to make the plate of springy material and fasten it at one end, e, tothe hasp A, and provide room, as at a', for the free end e ofthe plateto vibrate in. The platcis provided with projections e2 e2 e?,corresponding to the recesses d3 d3 da in the latch projection d2, andwhen the latch projection is in the frame, as inFig. 2, the projectionse2 e cL engage in the recesses d3 d d3. The projections e2 e`L e2 aresuitably shaped, and the plate E yields sufficiently to enable the latchprojection d2 to pass into the frame c,- but the latch D cannot beraised, as in Fig. l, until the plate projections e e2 c2 are disengagedfrom the recesses d3 d cl3.

F-represents the seal, usually of paper. It is held in the front of theframe a, and is therein supported against'a plate, G. This plate G isheld down in the frame c by means of the lugs g g, which pass throughopenings in the bottom of the frame a, and then clinched. This is aconvenient mode of attaching the plate in the frame, and by making thelugs to fit somewhat loosely in the frame-openings the plate ispractically hinged to the frame, so that when the latch projection d islifted out of the frame a. the plate G at its upper end can be turnedback in the frame insufficiently to admit the seal F in front of it.Until the plate G is thus turned back in the frame a, the flange g atthe top of the plate G prevents the seal from being lifted. rlhe latchDis also provided with a ilange, el, which, when the latch is down, comesover and bears upon the plate-iiange y', and thereby serves to coniinethe plate G within the frame a.

To open the lock, the procedure is as follows: The latch D, as stated,cannot be raised until the plate E is disengaged. `'Ihis is accomplishedas follows: The operator passes a rod through the seal, then through aperforationg2, in the plate G, then through a perforation, d5, in theprojection d, and presses the inner end ot' the rod against thespringplate E, and suiiiciently to press the plate E back from theprojection 12.l The operatorthen, with the point of the rod pressing theplate E backward, as described, lifts the latch and disengages it fromthc staple C; butin lifting the latch the seal is torn upward anddownward through a considerable portion of it, and enough to be readilyseen, even at a distance from the lock. The plate perforation g2 is inthe form of a slot, as indicated in Fig. 4: and show n in Fig. 1, toprovide for the move- IOO ment of the rod in opening the latch. The haspis provided with the eyes a3 a, through which the latch-pin d passes, asWell as through the staple C. This prevents strain upon the lock in casethe staple C is forced inward.

I claim- 1. The combination of the hasp having an open-faee frame, a,and a slot through one end, adapted to receive a staple, C, thespring-plate having one or more teeth on its free end, the latch D,having projections d d2, the latter being provided with one or inorerecesses to engage With the said spring-plate, and also with an opening,d5, substantially as described.

2. The combination of the hasp A, the franie a, the latch D, having therecessed projection di, the plate E, having the projection orprojections c, and the plaie G, substantially as described.

3. In a seal-lock haring a frame, a hasp, A, l

and the slotted plate G, attached to said frame a by lugs g,substantially as described.

4. IThe combination ofthe hasp A, provided with a frame, a, the latch D,a locking device therefor, consisting of the plate E, having one or moreprojections, c2, and the projection d, having recesses in its underside, and a perforation through projection di, the lange on the latch,and a perforated plate, G, substantially as described.

5. The combination of the hasp A, having an open-face frame, a, thepivoted latch D, having a perforated projection, d2, provided with oneor more catches on its under side, the toothed spring-catch E, and theplate G, substantially as described.
